Could anyone provide me with an example of how to create a filer saturation circuit? I now that the filter needs to be overdriven (gain) but it cant just be a case of more gain on input and sticking a distortion circuit in series.
I have kind of double posted this one in general discussion under the heading of pulsar modular corner.
filter saturation circuits?
Ok Well I found this floating around on the net at the pulsar yahoo user group. It seems to be simulating filter overdrive and allowing the user to crossfade smoothly from the original to the overdriven signal.
The obsidian module equivalents can be found in MOD III.

Here's an attempt at a more coherent version =P. You can't post file in this section, but you can in the Preset/Tools or Modular Patches forum, and link the thread over here.
